Assistant Research Scientist:

Dr. Zan Peeters completed his PhD at Leiden Institute of Chemistry where he focused on the analysis of organic molecules, their stability in different space environments and their subsequent role in the origin of life. He designed and built several space simulation chambers that were used to acquire data on the effects of UV photo-processing, temperature conditions, atmospheric conditions and the presence/absence of oxidizing agents on organic matter. He was sponsored by the Dutch Space Agency, SRON to prepare the “Organic” experiment for the EXPOSE facility on the International Space Station for flight. During his Postdoc fellowships at NASA Goddard and Carnegie Institution in DC, he expanded his research field to study organic matter in ice matrices as well as carbon-rich inclusions in meteorites. He was a Support scientist for the NanoSIMS laboratory at Academia Sinica in Taipei for 4 years.

In the current position at ASU, apart from doing independent research, he is also in charge of the daily operations of the NanoSIMS lab at ASU.

Postdoctoral Researcher:

Dr. Ziliang Jin received his Ph.D. at the China University of Geosciences, Beijing. His PhD thesis project was to study the genesis of Skarn-type iron deposits, which supply the highest grade iron ores in China. He also worked as a guest scientist in the GeoForschung Zentrum (GFZ) SIMS lab in Potsdam, Germany. Since matrix-matched reference materials are critical for SIMS experiments, he worked on the Cameca IMS 1280HR instrument to develop and characterize reference materials, such as the synthetic glass, synthetic olivine, apatite and calcite.

His current research work at ASU will focus on the study of volatile elements in anhydrous minerals from the asteroid Itokawa and other chondritic samples using the NanoSIMS 50L.

Graduate Students:

Zeb Teichert – He is currently a first year graduate student in SESE, and is being co-advised by me and Dr. Lynda Williams, an expert in terrestrial clays.  His interest is in using Li and B to trace the aqueous alteration and thermal history of organic matter in carbonaceous chondrite meteorites and terrestrial shales.

Melissa Sedler – She is a first year graduate student in SESE, and is doing her second project with me. Her research interests is in astrobiology and environmental biogeochemistry. She is trying to decipher the nitrogen cycle in extremophiles from the Yellowstone National Park, using single-cell measurements with the NanoSIMS.

Jonathan Zaloumis – He is a second year graduate student in SESE, and is doing his second project with me. His research is to determine biogenicity of microdigitate stromatolites, and to understand the potential for sulfate-rich veins as a biosignature in terrestrial rocks as analogs to Martial rocks, using the NanoSIMS.

Undergraduate Student:

Jack Schulte – He is currently an undergraduate in Barrett, the Honors College at Arizona State University studying Aerospace Engineering and Astrophysics. His main interests include stellar and planetary astrophysics, especially the study of presolar grains in meteorites. He is a private pilot and works part-time as an aircraft manager at Scottsdale Airport. He also owns a small reflecting telescope and spends an occasional night observing and photographing the Moon and neighboring planets.
